Does it cost money to sync music from PC to LG VX8550 Chocolate phone using V Cast?

I recently bought a LG VX8550 Chocolate from Verizon, but did not buy the additional V Cast feature. Because of the deal I got, I received a free essential music kit, which comes with the USB cord and program needed to sync music from my computer to phone. My phone allows me to access this feature, and I know the program is free to use.

Are there airtime charges or any sort of hidden fees that will show up if I transfer music?

I'd like to know this too.

What was your experience?
